The twenty-one papers that make up this volume reflect the broad perspective of African linguistic typology studies today. Where previous volumes would present language material from a very restricted area and perspective, the present contributions reflect the global interest and orientation of current African linguistic studies. The studies are nearly all implicational in nature.

Based upon a detailed survey of a particular linguistic phenomenon in a given language or language area conclusions are drawn about the general nature about this phenomenon in the languages of Africa and beyond. They represent as such a first step that may ultimately lead to a more thorough understanding of African linguistic structures. This approach is well justified. Taking the other road, attempting to pick out linguistic details from often fairly superficially documented languages runs the risk that the data and its implications for the structure investigated might be misunderstood. Consequentially only very few studies of this nature giving the very broad perspective, the overview of a particular structure type covering the whole African continent are represented here.
